Performance Report: Significantly slower calls to the user playlists endpoint on v1

Issue found of 27/10/2020

We noticed significantly slower performance when requesting data from the v1 user playlists endpoint vs the v2 implementation.

Although this is one particular example, we wonder if there might be other performance issues.

As we migrate back to the v1 tracks/playlists endpoints we will collect metrics and compare performances in case this information proves useful to SoundCloud.

Endpoint(s):

• GET https://api-v2.soundcloud.com/users/4269948/playlists
• GET https://api.soundcloud.com/users/4269948/playlists

Scope(s):

• None, (this request requires only a client id)

Expected behaviour

Comparible performance

Actual behaviour

v2 endpoint takes ~1s
v1 endpoint takes ~3s
